Jeffrey Yasskin	23ac706aab	Fix DenseMap iterator constness. ... This patch forbids implicit conversion of DenseMap::const_iterator to DenseMap::iterator which was possible because DenseMapIterator inherited (publicly) from DenseMapConstIterator. Conversion the other way around is now allowed as one may expect. The template DenseMapConstIterator is removed and the template parameter IsConst which specifies whether the iterator is constant is added to DenseMapIterator. Actually IsConst parameter is not necessary since the constness can be determined from KeyT but this is not relevant to the fix and can be addressed later.

Lang Hames	deed780bc6	The Indexes Patch. ... This introduces a new pass, SlotIndexes, which is responsible for numbering instructions for register allocation (and other clients). SlotIndexes numbering is designed to match the existing scheme, so this patch should not cause any changes in the generated code. For consistency, and to avoid naming confusion, LiveIndex has been renamed SlotIndex. The processImplicitDefs method of the LiveIntervals analysis has been moved into its own pass so that it can be run prior to SlotIndexes. This was necessary to match the existing numbering scheme. llvm-svn: 85979	2009-11-03 23:52:08 +00:00
